Incentives

State and local solar incentives in Wyoming

Beyond the 30 percent federal Residential Clean Energy Credit, which applies in every US state through 2032, Wyoming has these state and local programmes.

No state solar tax credit

Wyoming does not offer a state income tax credit for residential solar. Wyoming has no state income tax, so a state credit would not be applicable. The 30 percent federal Residential Clean Energy Credit remains the only tax-based incentive.

No state property-tax exemption

Wyoming does not have a statewide property-tax exemption for residential solar.

No state sales-tax exemption

Wyoming does not currently offer a sales-tax exemption for residential solar equipment. The standard 4 percent state sales tax plus local additions applies.

Permits and interconnection

Running a solar company in Wyoming

Running a solar company in Wyoming means working in a small market with limited installer competition. The best Wyoming operators handle both Rocky Mountain Power and Black Hills Energy interconnection fluently, understand the long-distance rural logistics of the state, and model winter cold-weather effects (snow derating, high-wind events) honestly. Lead costs run $80 to $150 on Google search, low because installer density is thin.

Questions people ask

Solar in Wyoming: FAQ

Does Wyoming have net metering?

Yes, retail-rate net metering for residential solar systems up to 25 kW AC at Rocky Mountain Power and Black Hills Energy under Public Service Commission rules. Credits accrue monthly at retail; annual true-up at year-end with excess paid at avoided cost.

How much does solar cost in Wyoming?

Residential solar in Wyoming averages around $2.85 per watt installed, meaning a typical 7 kW system costs about $20,000 gross. After the 30 percent federal tax credit, net cost is approximately $14,000. Wyoming has no state solar tax credit.

Is solar worth it in Wyoming?

For Wyoming homes with high electricity use and south-facing roofs, yes but with longer payback than retail-NEM states with higher electric rates: typically 12 to 15 years with the federal tax credit. Low electric rates (around $0.12 per kWh) stretch payback. Many Wyoming homeowners install solar for energy independence alongside payback.
